SAND-BOX FOR TRAM-CARS.

SPECIFICATION forming part of Letters Patent No. 345,768, dated July 20,1886.

(No model.)

To all whom it may concern:

Be it known that I, LOUIS DE L. CAMMANN, a citizen of the United States,and a resident of the city, county, and State of New York, have inventedcertain new and useful Improvements in Sand-Boxes for Tram-Oars, ofwhich the following is a specification.

My invention has for its object to provide a tram or other carw-ith.means of readily distributing sand, &o., adjacent to the wheels;and my invention consists in arranging sandhoppers provided with valvesadjacent to the wheels, and in combining therewith valveoperatingdevices, as fully described hereinafter, and shown in the accompanyingdrawings, in which- Figure 1 is a side view of sufficient of a tram-carto illustrate my invention. Fig. 2 is an inverted plan; Fig. 3, anenlarged view of the sandhopper and adjuncts.

The frame and running-gear of the car are constructed in any of thevarious different ways commonly employed in the manufacture oftram-cars, to any of which my invention is applicable.

In any suitable position 011 the car-platform 2A, preferably below theseat B, on each side,

and adjacent to one or more of the wheels, is a hopper, 0, containingsand.

In the construction shown each hopper is formed by an extension of theside pieces, a a, of a metallic case or guard, D, extending over thewheel within the car, an end plate, I), and the curved guard-plate'e,con- ,1 stituting the edge plates of the hopper, which the periph ry ofthe wheel, so as to throw the sand close to, and, if possible, upon, thelatter, in which case the brakes are caused to take a much better hold,and the wheel prevented from sliding on the track.

The slides or valves are constructed with any suitable operatingmechanism. Thus a rock-shaft, G, is supported in hangers H, beneath thecar-platform, and is provided with arms i 2, extending into openings inthe slides, so that the latter are moved in and out by rocking theshaft. The shaft is turned in one direction by a spring coiled round thesame, the spring tending to keep the valve closed. The shaft is turnedin the opposite direction to open the valve by means of an operatinglever or levers on the platform adjacent to the operator.

When there are hoppers adjacent to both pairs of wheels, there are twooperating-levers and any suitable connections between the same and thevalves.

As shown, there is a foot-lever, I, on the platform connected by a rod,m, to an arm, a, on the valve operating shaft, and the spring, byturning the shaft, tends to keep the foot-plate F in an elevatedposition, so that it may be pressed down by the foot to open the valve.

When there are two sets of hoppers and it is desirable to throw eitherdevice out of operation, this is done by inserting a block under one ofthe foot-plates, thus preventing it from being depressed.

\Vithout limiting myself to the precise construction and arrangement ofparts shown, I claim- 1. The combination, with the wheel of a tram car,and with the platform, through which the wheel extends, of a sand-hopperabove the platform, with a spout extending through said platform, themouth of the spout being opposite and in close proximity to the tread ofthe wheel, to throw the sand thereon, and a valve and operatingappliances, Substantially as described.

2. The combination of the carwheel, guard extending over the same, andsand-hopper I provided with a valve, and formed by an extension of theside plates of the guard, and by an edge plate, I), substantially asdescribed.

3. The combination ofv the wheel, sand-hopper case 1), covering thewheel above the platform, sliding valve, and operating-lever connectedto said valve, substantially as described.

4. The combination, with the hoppers above the platform, spouts, slidevalves, and opto this specification in the presence of two suberzttinglever and connections, of a rockscribing witnesses. shaft provided witharms extending through Openings in the valves, and a foot-lever con 5nected to the rock-shaft, substantially as de- W'itnesses:

scribed. W. DE L. WILKINS.

In testimony whereof I have signed my name CHARLES T. AUSTIN.

LOUIS DE L. OAMMANN.
